* During my searching for information, I found quite
a few discrepancies in the sources I was viewing. In light of this, the 'Year'
entry, as indicated by the chart below, may actually represent the year that

an automobile.

** Also note... the combustion chamber volumes shown
in the chart are based on various sources. Never assume that the volume is
at stock spec. Always have your chamber volume measured, especially if you
will be pushing the limit of an acceptable compression ratio for your combo.
